Download or read book The Effect of Different Cold Storage Conditions on Extra Virgin Olive Oil written by Xueqi Li and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Storage conditions can affect the stability and quality of extra virgin olive oil (EVOO). While many studies have reported the effects of high temperature and light exposure during storage, little is known on the effect of the cold storage. The aim of this study was to evaluate the effect of different storage conditions (25 °C, 4.5 °C and -27 °C) on the quality of EVOO and to determine if cold storage will prolong shelf-life by retarding hydrolysis and oxidation. Oil samples were stored in the dark and tested periodically. The AOCS official methods were applied to determine the basic physical-chemical parameters including free fatty acids, peroxide value and ultraviolet absorption. Natural antioxidants such as alpha-tocopherol and phenolic compounds were also measured. Due to the important health-conferring and sensory properties of phenolic compounds, this study focused on the change of main phenolic compounds with higher anti-oxidative abilities such as tyrosol, hydroxytyrosol during storage. The characterization/quantification of phenolics was achieved by ultra performance liquid chromatography - diode array detector (UPLC-DAD) with less solvent usage and shorter total run time (15min). In addition, 1,2-diacylglycerols (DAGs) and pyropheophytin a (PPP) were measured to better indicate the thermal degradation level during storage. At the end, a sensory test was conducted, though no significance observed. Statistical analysis confirmed the significant differences among different storage conditions in terms of quality parameters.

Download or read book The Nemechek Protocol for Autism and Developmental Disorders written by Dr Patrick M Nemechek D O and published by Createspace Independent Publishing Platform. This book was released on 2017-09-04 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Nemechek Protocol for Autism and Developmental Delay is the most scientific and refined approach to reversing the devastating effects of autism, ADD, ADHD, SPD and the myriad of other developmental disorders. Dr. Nemechek's approach frequently triggers rapid and often breath-taking improvements in children within only a few weeks. And surprisingly, the protocol employs common and natural supplements, and avoids the countless homeopathic remedies and antibiotics frequently prescribed to children that are often both toxic and expensive. Within a few days of starting the protocol many children will experience a connectedness to their surrounds never previously experienced. Significant improvements in motor, sensory and speech delays are realized within the first few weeks. Attention and learning disabilities rapidly begin to resolve within the first few weeks to months as the child's brain restores neuronal pathways damaged by the physical, emotional and inflammatory traumas commonly experienced in childhood. Through a simple 2-step process of re-balancing intestinal bacteria and omega fatty acids, Dr. Nemechek has discovered how to re-activate the brain's neuronal pruning and repair processes thereby allowing a child's brain to begin repairing past injuries and developing correctly. Re-balancing intestinal bacteria also eliminates the excessive production of propionic acid that is responsible for the disconnected and often strange behaviors that are highly characteristic of autism. With the help of Jean Nemechek's writing and editing style, the complexities of omega fatty acids restoration, intestinal bacteriology, autonomic restoration and cumulative brain injury are translated into processes that are easily understandable to the non-scientist. This book is a complete how-to guide outlining the specific supplements and dosages employed by Dr. Nemechek in the treatment of his patients. Readers will learn Dr. Nemechek's step-by-step method of reversing autism and other developmental disorders. Included are specific chapters dealing with relapses, addressing the use of antibiotics, strategies for prevention as well as future vaccinations. The rapid rate of improvement seen with The Nemechek Protocol has caused it to become one of the fastest growing treatment options for children around the world. Thousands of families around the world are benefitting from this safe, inexpensive and highly effective treatment for the devastating problems commonly affecting children today. The phrase "Miracles do Happen" has never been as true when witnessing children regain speech within a few weeks to months after utilizing The Nemechek Protocol.
Download or read book Extra Virgin Olive Oil Quality Safety and Authenticity written by Theodoros Varzakas and published by Mdpi AG. This book was released on 2021-11-12 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The prevention and bioactivity effects associated with the so-called "Mediterranean diet" make olive oil the most consumed edible fat in the food intake of the Mediterranean basin. The road to quality demands that legislation should be followed. Hence, official European Union classifications such as protected designation of origin (PDO), protected geographical indication (PGI), etc. guarantee the quality and the origin of the labeled foodstuff. The profiling of volatile components and the aroma of olive oil are key factors in the quality dimension and are affected by various factors and conditions such as cultivar; atmospheric, pedologic, and fostering conditions; the ripening degree; olive and oil storage; and the technology of oil extraction from drupes, as well as the quality of the pre-extraction procedures. In extra virgin olive oil production, as in all kinds of production, the maintenance of high quality standards is assured by the olive fruits' and the final products' quality. Modern milling technologies can aid in the direction of quality and safety and thus can be employed in the production of extra virgin olive oil (EVOO), which can be directly consumed without any further manipulation. The overall quality of EVOO should be determined by quality characteristics including sensory analysis, stability, and nutritional value and safety (microbiology, absence of contaminants and toxins), along with authenticity. Food authenticity issues are very important for the food industry due to legislation aspects, economics, quality specifications and conformance, safety concerns, and religious matters. Authentic EVOO should comply with the producer's declaration regarding the quality of olive fruits, natural components, the absence of extraneous substances, production technology, the geographical and botanical origin, the production year, and the genetic identity. Hence, olive oil authenticity can be implemented by the validation of the application of accurate specifications for olive fruits and the selection of trustworthy suppliers with a quality assurance system in place. Authenticity methodologies will avoid adulteration but will also aid the control of accidental contaminations, e.g., in factories, where several oils are produced or used at the same time, or cross-contaminations.
